## Possible Solution

No idea. The storage driver for Opensearch does something wrong?

## Steps to Reproduce (for bugs)

It happens on its own.

The API from Opensearch seems to give proper information:
```
$ curl -k -X GET "https://admin:passwowrd@data1:9200/_cat/indices/gl-events_*?format=json&h=index%2Cstatus&s=index%2Cstatus&expand_wildcards=all&pretty"
[
{
"index" : "gl-events_10",
"status" : "open"
},
{
"index" : "gl-events_11",
"status" : "open"
},
{
"index" : "gl-events_12",
"status" : "open"
},
{
"index" : "gl-events_3",
"status" : "open"
},
{
"index" : "gl-events_4",
"status" : "open"
},
{
"index" : "gl-events_5",
"status" : "open"
},
{
"index" : "gl-events_6",
"status" : "open"
},
{
"index" : "gl-events_7",
"status" : "open"
},
{
"index" : "gl-events_8",
"status" : "open"
},
{
"index" : "gl-events_9",
"status" : "open"
}
]

```

## Context

I have no idea what this might cause.
